| Abstract: | ObjectiveTo examine effects of Lycopene(LP)on cognitive function in ischemia-reperfusion rat models caused by middle cerebral artery obstruction(MCAO).MethodsMCAO rat models were set up and effects of LP were detected on cognitive function in rat models with Morris water maze and Y maze test.ResultsAverage swimming speed of rats in water maze dropped significantly after MCAO,required training numbers need for avoiding electric shock in Y maze increased significantly.Compared with model group rats,average swimming speed of rats in water maze in low dose LP and high dose LP group increased significantly,training numbers need for avoiding electric shock in Y maze in low dose LP and high dose LP group decreased significantly.ConclusionLycopene improves cognitive function in ischemia-reperfusion rat models. |
